Diagnosis of Rosacea

Your doctor will ask about your symptoms and medical and family history. A physical exam will be done, including a thorough examination of your skin. The diagnosis can usually be made based on the typical appearance of the rash. In some situations, you may be referred to a doctor specializing in skin problems (a dermatologist) or eye problems (an ophthalmologist). There are no specific tests to detect rosacea, but some testing may be done to rule out other disorders with similar symptoms. These may include blood tests or a skin biopsy.

The National Rosacea Society's experts have created a system for diagnosing rosacea that includes specific symptoms being present for 3 months or more.

The diagnosis will include identification of the subtype. Knowing the subtype of rosacea can help with a treatment plan. There are 4 subtypes:

Erythematotelangiectatic rosacea (subtype 1)—Flushing and persistent redness, which may or may not include visible blood vessels.
